"Going Underground"

Discover a Different Side of Surrey

Saturday 9 May is Surrey Day – and this year, we’re digging deeper.

Now in its eighth year, Surrey Day is about bringing communities together to celebrate everything that makes this county so special. In 2026, the theme is Going Underground, and it’s an invitation to see Surrey as you’ve never seen it before. Forget what you think you know about this beautiful county. Beneath the rolling hills and the familiar high streets of its market towns lies a world of hidden treasures just waiting to be unearthed.

Whether you fancy venturing into the literal underground or uncovering something altogether more unexpected, Surrey Day 2026 has something to spark the curiosity of all the family. Enjoy hands-on activities, torchlit tours, guided walks, unseen histories, a disco in a tunnel and stories in caves, re-enactments in shelters, castles to explore, fossils galore – and so much more!

While there will be events and activities countywide, this year, Epsom is taking centre stage as a key host town for the very first time. BBC Radio Surrey will be broadcasting live from Epsom from 12-3pm so keep your ears open – or better still, get down there and join in! The headline act is the extraordinary Ashley Road Deep Level Air Raid Shelter – a grid of brick-lined tunnels constructed 50 feet underground to shelter 1,500 people from the Blitz. Now hidden in woodland on the edge of town, there will be torchlit guided tours, but book early as these will sell out.

Many Surrey museums will also have Going Underground events such as Bourne Hall Museum in Ewell with an exciting full day of discovery, including an archaeological walk-and-talk, coin identification drop-ins and the remarkable story of the Epsom Aurochs which was a 3,500-year-old giant prehistoric animal unearthed locally in 2023. Or nearby in Dorking, there are castle and cave tours, guided history walks, and a chance to get hands-on with fascinating old inventions at Dorking Museum & Heritage Centre. A particular highlight is an impressively large-scale reconstruction of the very first Baronyx fossil discovery. On the other side of the county, Guildford Museum has fun hands-on fossil handling sessions, while Surrey History Centre presents a day of talks celebrating some of Surrey’s lesser-known artists. At Brookwood, you can be taken on a guided tour of the American Military Cemetery or if you head out further towards Tilford, you can get involved in 2 thrilling days of re-enactments at the open-air Rural Life Living Museum, finding out what daily life was like amid rationing and air-raids. If you’ve never visited, this is an experience you won’t forget in a hurry!
